Application filed July 19. 1909. Serial No. 508,443.

The invention is illustrated in the aeeom.

panying drawings. in whieh---- Figure l is a plan view of a blank which eonstitutes my improved fastener; Fig. 2 is a seetion al view of a box with the fastener applied: and Fig. a similar view showing how the auxiliary. fastening deviee ae- 'tuates in ease the holding tongue should be aeeidentally bent up.

Referring by reference eharaeters to this drawing, the numeral 1 designates a box of pasteboard or eardboard. such as designed for shipping small articles through the mails, and 2 the eoverthereofl 3 designates the fastener which is designed to be applied to eaeh end of the, box, as shown in Fig. 2, and \Yhitll has side wings -t whieh are bent at right angles, and inserted through slits in the edge, of the, box

and bent over to hold the fastener in plaee. The tongue is designed to pass through a slit in the rover, as shown, and then be bentover the end of the cover on the outside, as shown in Fig. 2, to hold the eover in place. Centrally of the body of the fastener is provided an auxil ary tongue (3 formed by slitting the metal of the fastener, and when the train tongue is in the position shown in Fig. '3. this auxiliary tongue lies [lush with the body of the fastener. as shown, as it does also when the fastener is first applied to the box. Should, however. the main fastening or holding tongue be aeeidentallv bent up during transit in the mails. rendering the eover liable to eome oil", the bending up of the main tongue wilt eause the auxiliary tongue to be bent or int-lined outwardly against the inside of the eover of the box, as

shown in Fig It. and thereby art. as a pawl or engaging deviee to prevent the accidental displaeement of the eover. The inside of the rover may be not'ehed or scored to assist in the holding aetion.

Having thus deseribed my invention what I elaim is:--

In eombinat'ion with a box and its cover having a slit therein. a fastener seeured to the box and having a foldabl e eover engaging tongue passing through the slit, said fastener having an integral auxiliary tongue for engaging the inside faee of the cover, said auxiliary tongue having its base in proximity to the line of fold of the main tongue whereby it will be moved outward into engagement with the eover when the main tongue is straightened, substantially as deseribed.

In testimony whereof, I affix my signature in presence of two witnesses.

CHARLES 0. MASON.
